TI - Syntheses of fused tetrahydro-β-carboline analogues through imide carbonyl activation using BBr3: evidence for the involvement of fused cyclic N-acyliminium ion intermediate SN - 09743626 AV - QD31 JOU PY - 2015/// CY - Bangalore PB - Springer KW - Intramolecular cyclization KW - Fused cyclic N-acyliminium ion KW - Tetrahydro-β-carboline N2 - The fused cyclic N-acyliminium ion generated during the imide carbonyl activation reaction of phenethylphthalimide was confirmed by single crystal X-ray diffraction. The Lewis acid assisted imide carbonyl activation methodology was successfully extended to synthesize fused tetrahydro-β-carboline units from the corresponding N-indolylethylimides UR - https://doi.org/10.1007/s12039-015-0836-8 ER -
